. 2-Claims. (Cl. 242-465) My present invention relates to improvementsin spool holders and more particularly to those types of holders adaptedprimarily for use in the manufacture of artificial silk.

In the manufacture of artificial silk and the like a suitable cellulosicsolution is spun into a coagulatingmedium and then collected on spools.Each spool is mounted on a spool holder secured to a rotatable shaft,and the thread is laid thereon by leading the same over a reciprocatingor oscillating guide. Since the thread is usually spun into acoagulating bath of acid reaction, the spool holders now in use arereadily attacked by the liquid of said bath resulting in the necessityof a. frequent replacement of the spool holders. Many types of spoolholders are known to the trade which have been designed to overcome thisdifficulty. The use of aluminum spool holders has been proven to beunsatisfactory since the aluminum is dissolved by the acid of thecoagulating bath and causes the formation of aluminum spots on the yarnwhen dyed. The use of other metals has been suggested but these are opento the same objections or are impracticable to use on a commercialscale.

It is therefore an object of my present invention to provide a new typeof spool holder which will obviate the abovedificulties.

It is another object of my invention to provide suitable means forclamping the spool to the spool holder and at thesame. time be of such aconstruction that the same may be readily replaced when worn orotherwise rendered unfit for further service.

These and other objects of my present invention will become moreapparent from a study of the following description and by reference tothe accompanying drawing in which:

Figure 1 is a section View of my" new spool holder on the line 1--1 ofFigure 2 showing the same secured to the spool shaft;

Figure 2 is a top-plan view thereof; and

Figure 3 is a detailed view of the spool holding means.

Referring now more particularly to the drawing, I have disclosed thereona preferred form of my invention. The base 10, made of hard rubber orother acid resistant material, is provided with a centrally located bore11 adapted to receive the blade 12 of the spindle (not shown). Thisblade is threaded on its outer end and the spool holder is securedtheretoby any conven ient locking means as by nut 13, and is providedwith a shoulder 12 against which the base is held by the said nut. It isimperative to insure a perfect rotation of the spool during the spinningoperation that the bore be located centrally of the base. l

Formed integrally with the base is' an upwardly extending hollowsubstantially cylindrical body member 14, the circumference of which isless than that V:ibf .the base thus providing a suitable seat 15 for,the end of the spool 16. A plurality of rectangular slots 17, preferablythree in number, are formed in the wall of the ,hollow cylino5 dricalmember adjacent the outer' end thereof and are adapted to receive thespool locking means. A

The locking] means, shown in detail in Figure 3, each consists of asubstantially rectangular 7o member 18 cut away at19 to form a shoulder20 to limit the movement of same locking means in the slot providedtherefor in the hollow cylindrical member 14. The outer end 21 of thelocking member is wing shaped and the lip of veach wing is formed ofstiff rubber. Since the inner end of Aeach locking member is largerthanv the slot in the cylindrical member within which it fits, I haveprovided a slot or cut-out portion 22 so that the furcations thusproduced may be bent toward so each other suflicientlyvto permitinsertion thereof in the slot in the cylindrical member.

In operation each of the slots in the cylindrical member is providedwith one of these locking or holding members. The spool is then forcedover the latter flattening the wing portions as indicated in dottedlines in Figure 2. 'Ihis causes the holding means to be pressed againstthe inner walls of the spool with sufficient force to hold the saidspool securely on the spool holder. v

From the above description it will readily be appreciated that I haveprovided a novel type of spool holder the construction of which-is suchas to render the same resistant against acids contained in the "spinningor coagulating bath. Moreover the device is constructed of few partswhich are of such acharacter that should any one of them become damagedit may readily be replaced without necessitating thediscarding of theentire assembly.

Although I have described in detail'the preferred form of my invention,it is obvious that many modifications in the construction thereof may bemade without departing from the spirit of my invention .or the scope ofthe appended claims. 05

What I claim as new is:

1. In a spool holder comprising an opening formed therein adapted toreceive a spindle blade; means to hold a spool thereon comprising ahollow member extending upwardly from said' base 110 upwardly from saidbase and having a plurality of spaced openings formed therein, holdingmeans having wing shaped outer ends secured in said openings adapted tobear resiliently against said spool, the inner ends thereof beingbiiurcated and shouldered to limit the outward movement of said membersin said openings.
